MammutMammut Mammut Assist Belay Resistor Gold

Mammut Assist Belay Resistor from Mammut is an assisted belay device for sport climbing, especially when there is a large weight difference between the belayer and the lead climber. It increases rope friction by being attached to the first quickdraw, allowing you as a lighter belayer to hold and lower a heavier climber more easily with good control.

The patented cam construction means that extra friction is only activated during a fall or lowering, providing soft catches and smooth handling otherwise. You can still belay dynamically, and the device is easy to release after it has been activated. With Boost Mode, you can also handle even greater weight differences, which reduces the risk of ground falls at the start of the route.
